During this invasion, expect foliage to be starved of vital nutrients. Infected vines have a yellowed, stunted and distorted appearance due to various toxins growing in brown-stained wood.

An invasion of woody tissue progresses, foliar symptoms become even more severe. This leads to a decline in productivity and may ultimately cause vine death.

What is Silver leaf?Silver leaf (Chondrostereum purpureum) is a disease that effects both stone and pip fruit trees with rapid loss of production. Silver leaf is an airborne fungal infection that spreads mainly in late winter and early spring. Fungal spores are released during rain and infect via broken branches or pruning wounds. The symptoms become more noticeable as the season progresses.

Benefits of Greenseal:

Seals off pruning and grafting wounds for effective control of Euytpa Lata and Silver leaf.

Ready made applicator is easy to use and is refillable many times over.;

Application:

Once Eutypa dieback becomes so extensive that the entire vine is compromised, vine reconstruction strategies should be seriously considered if productivity is to be restored.

Be sure to apply Greenseal™ the same day as pruning cuts are made.

Make clean, smooth pruning cuts with sharp pruners or saws. This helps provide a good surface for the Greenseal™ application to adhere to.

Cut and train: The trunk is cut 10-20 cm below any signs of brown Eutypa staining and a new basal shoot is trained. This maintains the existing rootstock. Yield will be zero until a new vine structure becomes established.

Train and cut: A healthy shoot is selected from the base of the trunk a.nd trained up. The infected trunk is not removed until the new shoot is producing.
Depending on vine structure, size of pruning wounds made and pruning regime (spur or cane pruned), application rates of Greenseal™ will vary between 2ltrs to 8ltrs per ha.
